Anterior feet unequal, left largest in the only individual examined; carpus 

 long 1 , about three times as long as broad, and as long as the carapax, anterior 

 edge with three distant teeth, posterior marked with a few denticulations 

 near the articulations with the hand; hand broad, flat, with thumb included 

 sub-triangular in outline, but the lower edge, or anterior edge when folded in 

 repose, is regularly arched from the articulation round to the tip of the finger, 

 palmar portion as long as the carpus ; finger and thumb with their opposing 

 edges straight, without teeth, slightly hooked at tip; surface of carpus and 

 hand shining, but roughened with a multitude of exceedingly minute granu- 

 lations on the upper surfaee ; on the lower the granulations are few and scat- 

 tered and the surface comparatively smooth and polished. 



Color of carapax aiad anterior, seen in the dry specimen, a beautiful red 

 verging on crimson. 



Geo. Distr. — Gulf of Mexico; a single specimen brought from Vera Cruz 

 by Dr. Cleveland, of Charleston. Distinguished by the large size of its hands 

 compared with the body, and the polished red surface of the carapax and an- 

 terior feet. 



Remarks. — The antennae are not represented in the figure, as they 

 were mutilated hi the specimen from which the drawing was made. The 

 figure gives too much the appearance of longitudinal rugse, which do not ex- 

 ist, as the carapax is perfectly smooth and polished.
